Great video, thanks for sharing. I took a Lee case trimmer and used a solid brass jag, which just barely fit into a 44 mag case. Let the point extend through the primer pocker. I then took two steel drill stops (Less than 4.00 at home depot) and joined the cutter and jag together. You can use super glue to join the cutter and 44 case and let it bond over time. Use the threads on the jag. Put a small washer and nut on the jag threaded end to tighten against the 44 case. works well. It leaves plenty of threads for attaching to the prep center.
